A head unit, in which unit head rows are formed by respectively arraying unit heads in parallel on both sides of a transmission substrate. The head unit includes a first liquid fluid channel that is disposed on a first side of the transmission substrate and a second liquid fluid channel that is disposed on a second side of the transmission substrate. The unit heads are provided with a flexible cable. A first head fluid channel sandwiches the flexible cable and is provided on a side that is opposite a transmission substrate side. A second head fluid channel is provided on the transmission substrate side. The first head fluid channel is in communication with a first liquid fluid channel on a surface side on which the unit heads are disposed. The second head fluid channel straddles the transmission substrate and is in communication with a second liquid fluid channel on a surface side that is opposite the unit heads.
